· JVASP-33808· PmCl3

Promethium trichloride (PmCl₃) is an ionic ceramic compound composed of promethium and chlorine, belonging to the rare-earth halide ceramic family. This material is primarily of research and specialized industrial interest rather than widespread engineering application, with use cases concentrated in nuclear science, radiation sources, and advanced materials research where promethium's radioactive properties are essential. PmCl₃ is notable for its role in developing luminescent materials, radioisotope power sources, and as a precursor compound in rare-earth chemistry, though its handling requires specialized facilities due to promethium-147's beta-emitting characteristics and the material's relative scarcity.
